New DCFD/MPDC TRS on 700MHz?

[m4a3t]

As do I. Fire, EMS, Services talkgroup coming in clear on the 800mhz system.

[m4a3t]

I also plugged in the control channels on the new MPD 700MHz system. I've monitored traffic on TG1039 as Citywide. I've yet to hear other radio traffic, ie Fire, EMS or Services on this system. Will this be exclusive to the police department?

It appears that the relevant licenses for the 800 MHz control channels are:
KNJE616
KNJU834
WPXT459

The 700 MHz channels were licensed with the call sign:
WQHY490
for the band 763-768 MHz.
But that license was an STA that expired on 12/25/2010.
Maybe they've reapplied for the STA and it hasn't yet been entered into the FCC's database.

WPTZ766 is good until 5/14/2017 for 769-775 and 799-805.

I ran pro96com and came up with a better looking channel plan.

FWIW --

While in the northern DC area today I listened with my PSR800 and had Pro96Com running for about an hour.

As with the other new systems coming online, you pretty much have to be in the city to pick them up.

TGID 1039 appeared to be FDMA (Phase 1) and the only talkgroup that was UNencrypted.

There were 9 other talkgroups active at various times - always TDMA (Phase 2):

11025, 11027, 11029, 11031, 11033, 11035, 11037, 11049, 11053, and 11061

Pro96Com detected 200+ radio IDs during the time - about half in the 5 digit range (23xxx - 65xxx) and the rest mostly 110xxxx - 111xxxx.

I was only there for a short period of time but there is quite a bit of activity for a Sunday afternoon - certainly to be more as time goes on.

DC Fire was still active on the "old" trunked system...

Not necessarily. Today was rehearsal day.

MPDC will be the inital primary user of the system. When they are all transitioned over (TDMA), DCFD will then start the process will be FDMA on the same system. The rest of the city will transition over and will be a true WashDC radio system bringing all the district agencies under one system.

Fire will be FDMA? Just at first for will it stay FDMA? Are reason why they won't be TDMA?

Powers that be wanted it that way for now. Besides, if you have a bunch of Phase 1 radios in service, why spend 5k per radio for new ones when you don't need to (or have the money to)

If you know something that can be divulged why don't you tell us what it is? Why all the cryptic comments about how we'll find out eventually? You've put several posts in this thread that all say essentially the same thing, which is that you know something that we don't know but you're keeping it to yourself. I don't get it.

[PJH]

Well, for this thread...there are certain posters here that belong to other lists that have stated that they cannot believe that such a system is online and that everyones scanner is showing them false information and basically saying that those of us in the know are lying/making things up and certain scanner users don't know what they are doing so it MUST be wrong.

Also, some information is covered by NDA's and cannot be divulged on the risk of severe penalties which I am not going to endanger myself with for the pleasure of a message board.

I imagine since they're already on 800, they'll keep the radios they already have and get them reflashed to support 9600 if they don't already.

I'd be happy with what little bit of hints he is willing to drop, it's not much but there are some things he's mentioned that have given a basic timeline or idea of what's going on.

I'm excited to see what this system is going to develop into, it'll sure be sad to see such a unique dual-band system get put out to pasture in the coming months/years.

FINALLY! Something that makes some sense from a $$$ perspective.... but wait, from the documents I've seen, this system costs $50-60 million dollars! For that, I'd think they'd get new radios too... At that price, I'd hate to see what the price would be for something like the size of Texas!

If you saw what the site equipment alone costs... then add all the other stuff...its just not cheap.

You can say that again.

[PJH]

Lets put it this way....

Under my contract pricing, an APX7000 configured pretty close and bare bones that would work on that system shows:

APX7000 DIGITAL PORTABLE RADIO - PACKAGE 2,105.60
LARGE COLOR DISPLAY 400.00
ENABLE DUAL BAND OPERATION 800.00
ASTRO DIGITAL CAI OPERATION 412.00
SMARTZONE OPERATION 1,200.00
P25 9600 BAUD TRUNKING 240.00
ADVANCED SYSTEM KEY

$5157...thats each

For the GTR8000 repeater...

$5000 for the radio
$5200 for 700/800 band
$8800 ASTRO25 software

then add in some more extra's that you need - and thats just the radio. Multiply that per freq, (times) sites. Your looking at $20,000 per radio. Add RF cables, preselectors, mounting hardware, duplexers, filters, blah blah. Keep adding in shelters, towers, battery backups, generators, datalinks more blah blah. We haven't even started to touch the console electronics, AEB (lets start at $250,000 for the AEB).

$3000 in ""options" on a $2000 radio "package" -- I'm glad I don't buy a car this way.

Has anyone attempted to program a Pro-96 on the new P25 DC TRS?

I am wondering if it will work at all. I know the Pro-96 will not trunktrack if the CC is in the 380mhz or 700mhz bands. But since this new P25 TRS has a control channel in the 800mhz band; maybe the Pro-96 can track it. My hopes are very low for this since the actual voice channels are all in the 700mhz band.
